This book starts really well with an interesting take on the idea that many successes arise from trial and error, and it's important to learn from what doesn't work. Tim Harford gives some novel examples on how individuals have managed to overcome "group think" and achieved success by breaking the established mode of doing things. Unfortunately, after a few chapters, I felt that there was some repetition and the book lost it's "aliveness". It seemed as though he had an idea for a book but then ran out things to say, so kept saying the same thing in a different way. Perhaps would have been better for being a shorter book with less repetition

This is a nicely balanced book, and it's very coherent. It draws together an argument that links the essential processes of evolution (variation, selection), and the idea of isolating and containing failure. Since failure is inevitable in complex environments, and a lot of modern life involves complex systems, the primary argument is therefore that we should anticipate failure and incorporate it in our organizations and policies. In more abstract terms, it's like using evolution as a search algorithm in a complex space - a concept I find very appealing.
Sprinkled throughout the book are supporting examples, some of which are covered in detail. A couple of chapters single out climate change and the financial meltdown as distinct examples of complex systems that would benefit from this kind of thinking.
It's one of the books I've made the most notes for on my Kindle; not necesarily because the points are profound, but because I liked the way they were expressed. There were a few aspects which I felt might have been a bit over-emphasised - a few references to a kind of macromutation, which I think is stretching the analogy a bit too far; and a few bits where I felt references were needed -- but I can't fault the book overall.

I'm not sure entirely who is expected to buy this latest book by Tim Harford, but I wonder if the person-in-the-street, such as myself, might just be a suitable audience, rather than other economists.
My knowledge of economics is extremely basic. I've read some of a book (in German) by a German economist friend, and I listen to More or Less on Radio 4, which is of course presented by Tim Harford. His excellent presentation style on that programme made me pick up this book with some anticipation.
I wasn't disappointed. The same friendly, chatty style appears throughout this book. Things are explained clearly and efficiently and you aren't left feeling like you're a bit thick if you aren't conversant with the latest economic theory. The book abounds with examples in daily life of what he's talking about, whether it's military engagements by the US army or employee benefits in Timpsons the keycutters. It made the book always interesting and lent authority to his arguments.
The book is very well structured with chapters dealing with overall situations (such as the Afghanistan/Iraq wars, climate change, the financial crisis, business structure) but broken down into many subheadings which mean it's easy to pick the book up and read for a few minutes without completely losing the thread. Tim Harford's research and wide-ranging knowledge help to make this a fascinating read.
I did feel that at times there was a fairly black and white presentation of events, particularly with regard to the hugely complex Afghanistan conflict. It was as if "it was all going wrong, and then someone adapted/came up with a new plan and now it's great." Undoubtedly many of these adaptations made a significant difference but I wasn't convinced they were quite as magic-bullet as I felt they were portrayed. Another example is talking about the way some companies are structured. One of the companies mentioned in glowing terms throughout is one that an acquaintance works for and their story is somewhat different about life in that business. As always, there are many facets of each situation and life is complex but I felt that this didn't always come across in this book.
However, for an economics newbie such as myself it was a really good introduction to Harford's theme of adaptation - that innovation and variety are key to the health of economies, businesses, and more.

I am a fan of Tim Harford. His two previous books, The Undercover Economist and The Logic of Life are favourites of mine and this, his latest book, is possibly his best so far.
Much of what we read about the World in the media is ill-informed, inaccurate clap-trap. As an Economist, Tim Harford bases his observations upon measurable data which so often reveals that the way the World actually works, is very different from the way we think it works or the way we might want it to work.
This book is a bit different from the two that came before. It could be classed as a self-help book, in that it's central theme is that none of us are smart enough to know in advance what will succeed and what will fail and that the secret to a useful and satisfying life is to recognize this, be willing to conduct dumb experiments and accept that failure is all part of the game of life. If you don't experiment, you never fail, but then you can never win either. Successful people and organizations fail a lot, but when they will they do succeed, they do so in big ways.
The logic is tightly argued and examples are drawn from many topical examples, like the Iraq war, international aid programs and the banking crisis. Tim Harford's lucid, jargon free style coupled with his mastery of the topics and his central theme, provides fresh insight into why events unfolded as they did.
This is an easy and entertaining read that serves-up some valuable lessons to organizations and individuals alike.
After reading and then re-reading this book, I remain unconvinced that success [begin italics] always [end italics] starts with failure but agree with Tim Harford that it frequently does, usually through a process of trial and error in combination with experimentation and elimination. There are two keys to the success of that process: learn from each error, and, do not repeat it. Long ago, Charles Darwin observed, "It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change." I was again reminded of that observation as I began to work my way through Tim Hartford's lively and eloquent narrative.
Here are his own thoughts about the resiliency that is required of those who seek success, however defined: "The ability to adapt requires a sense of security, an inner confidence that the cost of failure [what I prefer to view as non-success or not-as-yet-success] is a cost we will be able to bear. Sometimes that takes real courage; at other times all that is needed is the happy self-delusion of a lost three-year-old. Whatever its source, we need that willingness to risk failure. Without it, we will never succeed."
The quest for business success involves constant experimentation. Obviously, the prospects for success are improved substantially within a workplace culture that encourages, supports, recognizes, and rewards prudent experimentation. But, as with ideas, the more experiments that are conducted, the more likely that there will be a breakthrough. The first challenge to leaders is to establish such a culture; the next and greater challenge is to sustain it. Harford has written this book to help his reader respond effectively to both challenges. His approach is philosophical, yes, because there are significant issues with important implications and potential consequences to take into full account. However, in my opinion, his approach is also pragmatic and his recommendations are eminently do-able.
Peter Palchinsky (1875-1929) is one of the most fascinating people discussed in the book. He was a Russian industrial engineer (often viewed as a technocrat) whose progressive ideas about human rights during Stalin's consolidation of power led to several arrests and finally, execution by a firing squad. Here is Harford's brief but precise explanation of Palchinsky's principles: "First, try new things; second, try them in context where failure is survivable. But the third an critical step is how to react to failure...[to avoid] several oddities of the human brain that often prevent us from learning from our failures and becoming more successful...It seems to be the hardest thing in the world to admit that we have made a mistake and try to put it right."
These are among the dozens of passages of special interest and value to me, also listed to indicate the scope of Harford's coverage.
o The Soviet Union's "pathological inability to adapt" (Pages 21-27)
o Why learning from mistakes is hard (31-35)
o The Tal Afar experiment (50-56)
o Friedrich von Hayek and "knowledge of the particular circumstances of time and space" (74-78)
o Lottery tickets, positive black swans, and the importance of variation (83-86)
o Skunk Works and "freak machines" (86-89)
o "We should not try to design a better world. We should make better feedback loops." (140-143)
o The Greenhouse Effect, 1859 (154-156)
o The unexpected consequences of the Merton Rule" (169-174)
o Why safety systems bite back (186-190)
o Dominoes and zombie banks (200-202)
o Making experiments survivable (214-216)
o Adapting as we go along (221-224)
o Google's corporate strategy: have no corporate strategy (231-234)
o When companies become dinosaurs (239-244)
o "Challenge a status quo of your own making"(249-256)
Here is a brief excerpt from Chapter One: "We face a difficult challenge: the more complex and elusive our problems are, the more effective trial and error becomes, relative to the alternatives. Yet it is an approach that runs counter to our instincts, and to the way in which traditional organisations work. The aim of this book is to provide an answer to that challenge."

This is an inspiring and amusing argument for experimentation as a key strategic technique for the modern age. The book is full of amazing accounts of big plans that turned into epic disasters, from 19th century imperial Russian failures to organise mining to US military attempts to control Iraqi insurgencies and the recent meltdown of the banking sector. Harford compares those failures with successes such as the Spitfire airplane and Google's internet domination, suggesting the solution in the form of a checklist:
- Variation: seek out new ideas and try new things
- Survivability: try new things out at a scale where failure is survivable
- Selection: seek out feedback and learn from your mistakes as you go along
Harford calls this checklist the Palchinsky method, after an early 20th century Russian engineer Peter Palchinsky, who recognised that "real-world problems are more complex than we think", because of they have a human dimension and a local dimension, and are likely to change as circumstances change. I'm sure this will sound familiar to anyone who has ever been involved in a real-world software project. As the key aspects of this solution, Harford calls for adaptive planning and opening up lines of communication from the field to the planning office.
Harford focuses on innovation but also covers topics as diverse as the nature of mistakes, what causes latent errors that are not noticed until the very instant we can least afford them, strategic planning, effectiveness of expertise in today's fast-moving environment and isolating 'skunk-works' groups in large organisations.
This book deserves to be read by all business project and product sponsors, as well as anyone serious about delivering effective products and projects. If your boss needs convincing that lean startup ideas are good, and an explanation why It fits in nicely with the Lean Startup ideas, and explains why delivery plans should be more about options that could be explored instead of scope that is nailed down by committment. Authors strong views on climate change come through in the middle of the book where he argues about possible solutions, which I felt broke the reading flow and felt out of place in the book. However, the rest will surely be an interesting read for most people following my work. You'll be inspired by a ton of stories and great quotes. Here are some of my favourite ones:
- "Return on investment is simply not a useful way of thinking about new ideas and new technologies"
- "Ideal way to discover paths through a shifting landscape ... is to combine baby steps and speculative leaps"
- "For an organisation that needs to quickly correct its own mistakes, the org chart can be the worst possible road map"

This book brings a relatively simple message which is convincingly argued and illustrated by telling examples related to very topical subjects (climate change, how to tackle poverty, the financial meltdown, the war in Iraq...).
Harford posits that the world has become such a complicated place that it is not realistic to imagine that on basis of a rational analysis of data ready-made solutions on all problems can be found. It is more realistic to arrive at appropriate solutions by testing different scenarios, by evaluating them subsequently and selecting the solution best adapted to the circumstances. Failures are inherent to this method, however are useful and should lead to better solutions, hence the book's subtitle `Why success always starts with failure'.
As is amply shown by a wide range of examples a lot of companies and institutions have purely centralised organisations which ignore mostly the practical experiences of people in the field, with oftentimes awful consequences for these same people and catastrophic results for the whole organisation.
Harford demonstrates this by the experience of the American army in Iraq. The American defense secretary Ronald Rumsfeld was a dogmatic proponent of a centrally commanded army, which bases its top-down orders almost exclusively on its advanced information and communication technology. That the officers in the field needed some flexibility to react to local circumstances and that some instructions were utterly inappropriate was completely ignored by central command. This culminated in Ronald Rumsfeld not accepting reality and is tellingly illustrated by his stubborn, absurd refusal to use the word `insurgency' in a press-conference on Iraq, a word that most appropriately described the situation at that moment. The army became only more successful after systematically adopting strategies which had proven their practical worth in Iraq.
Confronted with complex challenges, companies do not have a do-for-all recipe to solve every problem and true expertise is hard to come by. The conclusions of a study on the efficiency/validity of expert-opinion is quite revealing: an evaluation showed that the value of the advice of these so-called experts was negligible.
As a result companies could be in a quandary to act if even the experts turn out to be of little help. Harford points out that biology could offer the answer by showing how species do adapt to different circumstances: variation and selection.
Companies should use the same strategy and adapt to their environment by trying out different strategies (variation) - however in such a way that the company can cope with a failure - and subsequently select the appropriate strategies. This method is not that evident as for organisations as well as for individuals it is difficult to accept failure, learning of them is not that easy either.
In order to be able to do an efficient selection process, it is of utmost importance that correct feedback is accepted and organised. Hierarchical companies function mostly by counteracting this correct information flow: people sugar-coat their opinions to their superiors who in the end get a very `political' impression of what happens.
Harford is an economist and this is obvious by the practical value attributed to the money motive to solve some of the main current problems: the most efficient way to tackle global warming is by taxing energy use, fraud in the financial world would be discovered earlier or more frequently by rewarding whistleblowers generously (Until now most whistleblowers have been de facto penalised for their denouncing frauds).
I did find it very revealing how Harford points out the similarities between the `failure' of the financial meltdown and an industrial catastrophe as for instance the explosion of the oil and gas rig Alpha Piper: Both are failures of very complicated systems with catastrophic consequences. How the disaster of the explosion of the Alpha Piper came about can be explained quite easily and the reader can vividly imagine how it all went wrong. It turns out that the financial meltdown was not that different, most likely more complex but - this is the most worrying - in this case safety measures were mostly non-existent or completely inappropriate. In industrial processes safety measures are taken almost for granted. It is disconcerting to be aware that no contingency plans exist(ed) in the case of the much more complex and more encompassing financial system.
This book brings home a very important lesson, shows it applicability to such diverse and important issues as poverty, global warming, the financial crisis... The myriad of well-chosen examples add to its attractiveness.
I hope this book is widely-read, understood and lessons are learned. We could all profit of that.
The breeding of bulldogs - Now a one person but two bulldog job with a special new hammock - personal space flight, the history of longitude, charter cities and US tactics in Iraq are just some of the subjects you can learn about in this very entertaining book.
The central thesis is that success always starts with failure. That's clearly the case with evolution and with markets. Progress takes place through variation and selection. The book considers the case for the same processes where markets don't operate. In armies fighting wars, in aid policy, in dealing with climate change, in the regulation of financial markets, in businesses and in out personal lives.
I have enjoyed reading every chapter of the book. But only th chapter on climate change is fully persuasive (bring on a carbon tax and markets). In the case of the US in Iraq, it's persuasive that the right answer was found on the ground and not at the top of the military chain of command. It's also persuasive that it would have been better for top commnders tone ore open to therm Ning ideas sooner. But there's no account given of all the variations you might need to encourage to find the winning one. Only the winning one gets a mention. Could you really fight a war or an insurgency on the basis that everyone does what seems best to them - and later we'll see what works? Maybe that's the best way, but Tim Harford is far from showing that.
Still, I did thoroughly enjoy reading it nd on that basis would recommend it to others.

I quite enjoyed reading this book. Harford is not afraid of taking his economic background into other non-economic spheres, which makes this book more of a how to manage and prevent disasters manual (disasters of all kinds... from economic meltdowns to nuclear plant meltdowns) then an economic book.
The message Harford delivers in his book is quite clear - as in science, one must experiment and be willing to fail, in order to find success, and while this is fine for science, it can be quite volatile in social science were the public is affected by wrong decisions which is why Harford recommends 3 basic rules:
1) always try new things, knowing that some will fail
2) always try to make failure survivable (as you expect to fail in some places)
3) always know when you've failed.
If you look at our current economic crises, it is quite obvious our economic leaders didn't follow rule 2. Harford does analyze the crises and does offer some solutions which are still relevant, even though the meltdown already happened.
This is a very enjoyable and readable account of human behaviour in the face of adversity, with a dash of economics thrown in for good measure. It takes as its main theme the proposition that success comes from adaption, through trial and error, rather than through a single moment of genius and examines US military ploicy in Iraq, the running of Google, and the evolution of a musical featuring the songs of Billy Joel, amongst much much else as examples, before conculuding that we must risk and accept failure in our personal lived in order to succeed.
Although there was not much that would be new to readers of business books here, apart from some of the examples, all this makes for very enjoyable light reading, and I felt quite inspired by the final chapter called 'Adapting and You'
